The Rock's rant was aimed at Fast 8 co-star Vin Diesel after it became 'almost impossible to shoot scenes'

UPDATE: Dwayne "The Rock" Johnson's social media rant was directed at Vin Diesel, and the pair have had a "secret meeting" to work out their differences, TMZ reports.

According to Fast 8 production sources, the buff action stars met up on Monday after The Rock blasted certain "chicken s---" male co-stars online.

Tensions are said to have flared because of Vin's role as a producer, making decisions that The Rock wasn't happy about.

The co-stars met up on the Atlanta set after it became "almost impossible to shoot scenes", TMZ claims. Most of the cast weren't fans of The Rock's public dig either – especially with only a week and a half to go on the production.

The 44-year-old earlier went off in an Instagram post targeting the unprofessionalism of some of his male co-stars on the action flick, calling the unnamed thesps "candy asses"...and sharing a super-short video reflecting his anger on set (see above).

"This is my final week of shooting Fast & Furious 8. There's no other franchise that gets my blood boiling more than this one," The Rock wrote. "An incredible, hard-working crew. Universal Studios Entertainment has been great partners as well. My female co-stars are always amazing and I love 'em."

Some of his male co-stars, though, not so much. "My male co-stars however are a different story," the actor continued. "Some conduct themselves as stand-up men and true professionals, while others don't. The ones that don't are too chicken s--- to do anything about it anyway. Candy asses. When you watch this movie next April - and it seems like I'm not acting in some of these scenes and my blood is legit boiling - you're right.

"Bottom line is it'll play great for the movie and fits this Hobbs character that's embedded in my DNA extremely well. The producer in me is happy about this part. Final week on FAST 8 and I will finish strong. ‪#‎IcemanCometh ‪#‎F8 ‪#‎ZeroToleranceForCandyAsses."

Whoa. The Rock didn't get specific about who exactly he was referring to, and none of his male co-stars have commented yet. Still, we, are curious who these "candy asses" are (and why they would do anything to anger this beyond buff actor).
